IddCxMonitorUpdateModes2 function (iddcx.h)

An indirect display driver calls IddCxMonitorUpdateModes2 to have the OS update the mode list for a monitor.

Syntax

NTSTATUS IddCxMonitorUpdateModes2(
  IDDCX_MONITOR               MonitorObject,
  const IDARG_IN_UPDATEMODES2 *pInArgs
);

Parameters

MonitorObject

[in] An IDDCX_MONITOR object that is the OS's context handle for the monitor. The OS provided this handle in a prior call to IddCxMonitorCreate.

pInArgs

[in] Pointer to an IDARG_IN_UPDATEMODES2 structure that contains the input arguments for this function.

Return value

IddCxMonitorUpdateModes2 returns STATUS_SUCCESS upon success; otherwise it returns an appropriate NTSTATUS error code.

Remarks

A driver can call IddCxMonitorUpdateModes2 to update the mode list previously reported for a monitor.

Drivers sending modes with SDR WCG or HDR parameters will fail if they have not also reported IDDCX_ADAPTER_FLAGS_CAN_PROCESS_FP16 in the IddCxAdapterInitAsync call. Also, drivers reporting IDDCX_ADAPTER_FLAGS_CAN_PROCESS_FP16 can only call IddCxMonitorUpdateModes2; calling IddCxMonitorUpdateModes is an error.

For more information about HDR support, see IddCx version 1.10 updates.
